Using AI nong to cold cloth for fruit trees for the winter

How to do well the cold work of citrus wintering

The temperature is low in winter and spring, and citrus young trees are susceptible to frost damage. The flower buds frostbite, the branches drain, the leaves are serious, causes the fruit tree yield and the quality to drop seriously; the serious person will appear the branches dry, the cortex freezes, even the whole plant freezes to death.

Next, Ai Nong.Cold clothManufacturers introduce the following effective anti-freezing measures, fruit farmers can refer to the use.

1. Application of fruit fertilizer and winter fertilizer: Young trees should be in the "snow" before the foot of winter fertilizer. Winter fertilizer to organic fertilizer mainly, organic fertilizer is not only conducive to improving toowin, protect the roots from frost damage, but also conducive to early spring timely supply of tree nutrition, reduce frost damage. Results The tree mainly applied heavy fertilizer before and after fruit picking, in order to replenish the nutrients consumed by the fruit, restore the tree potential, promote flower bud differentiation and enhance the wintering ability. Winter fertilizer should pay attention to the combination of quick-acting fertilizer and late-effect fertilizer application, accounting for about the annual fertilization of 30%~35%. The late ripening cultivars or mountainous arid or cold winter areas should be administered in November before harvest.


2. Timely soil: Before the arrival of frost to fertilize and carry out a soil, can effectively avoid the foundation and trunk suffered from frost damage. Soil to turf soil or soil 杂肥 soil as well. Each plant depends on the size of the canopy soil. Soil should be cultured to the upper part of the root neck, generally about 15 cm. If combined with mulch cover, the film Edge should be compacted with soil compaction. After low temperature, the soil above the root neck should be shoplifted in time to prevent rotten roots and diseases and insects from harming.


3. Irrigation: 7-10 days before frost, the Orange Tree irrigation, water storage temperature, reduce the temperature difference, so that during the cold ground temperature to maintain a relatively stable, thus reducing frost damage. Irrigation is best carried out at noon and in the evening with penetration.


4. Orchard cover grass and bandage trunk: The fruit lines cover straw, weeds, leaves, etc., can not only moisture conservation, but also maintain and improve the ground temperature. When the low temperature comes, straw can also be used to main branch the trunk tightly, effectively prevent the cold snap attack.


5. Cut off the late autumn tip: Citrus late autumn leaves thin color light, less organic accumulation, cell fluid nutrient concentration is low, easy to be affected by frost damage caused by deciduous leaves, so it should be cutting off.


6. Protect the canopy, remove the frost: after "heavy snow", fruit tree branches often have frost, not only easy to crush fruit branches, but also cause frost damage. Therefore, the frost on the branches should be cleared in time. Conditional usable films, straw, etc. cover the canopy of the orange orchard.


7. The trunk is painted white: combined with the orchard Winter Qing Garden, the fruit? Trunk Main Branch painted white. The formula of the white agent is: 2.5 kg of lime, 0.75 kg of sulfur powder, 1.25 kg of salt, 0.1 kg of vegetable oil and 18 kg of water. The preparation of lime, salt with hot water dissolved, fully stirred into a paste, and then added sulfur powder and vegetable oil, and finally with water, stir evenly and apply to the trunk.


8. Spraying hormones, etc.: spray 80 times times the oil emulsion liquid before and mid-December before the cold wave arrives. Citrus trees small can be properly diluted oil to prevent drug damage. Or in late November after the harvest, late December and mid-January, each spray high-fat film 200 times times Liquid 1 times. Early spring injection of naphthalene acetic acid solution, can delay the flowering period of citrus, avoid the harm of early spring low temperature, spraying concentration to 10 ml/kg is appropriate.


9. In addition to this, there is a very important measure, that is, to cover the citrus with cold and warm AI NongCold cloth。 Ai Nong Cold cloth use is very simple, do not have to build a shed, direct cover, but it has waterproof to protect against the cold, wind and frost, breathable and other excellent performance, equivalent to help the trees cover a quilt.
